“…Owing to its abundance, low toxicity, chemical and thermal stability, and resistance to photocorrosion, TiO 2 has been extensively studied as a catalyst for different photocatalytic reactions, [1][2][3][4] and used for paints, 5 coatings, 6 supports for drug delivery, 7 angiogenic agents 8 and so on. Crystalline TiO 2 itself has limited practical applications as a photocatalytic material because its activity is driven by ultraviolet (UV) light.…”

“…[8][9][10] The utilization of silver nanoparticles (AgNPs) that are prepared using environmental biodegradable polymers as both reductant and stabilizer [11][12][13][14] contributes to an improvement in the number of particles per unit region and thus, improve the antibacterial activity. [15][16][17][18][19][20] Because of the abundance of proteins containing sulfur on the bacterial cell membrane, AgNPs can react with proteins containing sulfur inside or outside the cell membrane, which in turn affects the viability of bacterial cells. It has been also suggested that silver ions (Ag + ) generated from AgNPs may interfere with phosphorus moieties in DNA, resulting in inactivation of DNA replication, or may respond with proteins containing sulfur, contributing to enzyme function inhibition.…”

The target of our current work was designed to prepare titanium oxide doped silver nanoparticles (Ag/TiO 2 NPs) and their impact on the functionalization of cotton fabrics. Additionally, the effect of Ag/TiO 2 NPs was compared with the individually prepared silver nanoparticles (AgNPs) and titanium oxide nanoparticles (TiO 2 NPs). In this work, AgNPs were prepared in the solid state using arabic gum as efficient stabilizing and reducing agent. Then, two concentrations of the as-synthesized nanoparticles were used to functionalize the cotton fabrics by pad-dry-cure treatment in the presence of fixing agent to increase the durability of treated cotton fabrics against vigorous washing cycles. The findings implied that the as-prepared nanoparticles were successfully synthesized in nano-size with spherical shape and homogeneity. The efficacy of the functionalized cotton fabrics with those nanoparticles were evaluated in terms of multifunctional properties including antimicrobial and ultraviolet protection factor (UPF) and the mechanical features before and after many washing cycles; 10, 15 and 20 times. The resultant also proved that Ag/TiO 2 NPs-treated cotton fabrics exhibited the greater values of both antimicrobial and UPF properties with enhancement in the tensile strength and elongation features. Thus, the combination between these two nanoparticles through doping reaction is suitable for imparting superior antimicrobial properties against the four tested microbial species (Staphylococcus aureus, Escherichia coli, Candida albicans, and Aspergillus niger) and good UPF properties. Depending on the promising obtained results of the multi-finishing fabrics, these nanoparticles of Ag/TiO 2 NPs can be applied for the production of an efficient medical clothes for doctors, nurses and bed sheets for patients in order to kill and prevent the spread of bacteria and then, reduce the transmission of infection to others.multifunctional fabric, silver nanoparticles, TiO 2 doped silver nanoparticles, TiO 2 nanoparticles | INTRODUCTIONThe main goal of textile finishing is to achieve sustainable modification especially with a low environmental impact along with saving time, reducing the cost of the utilized energy and also reducing the chemical usage.

This dissertation focused on the development of graphene (GO) nanocomposite coating to improve various substrate properties for the sensor application, which is divided into 2 main parts. The first part is the development of GO incorporated into electroless nickel phosphorus (NiP) coating to improve the properties of metal for electrochemical sensor application. Nickel phosphorus titanium dioxide sol � reduced graphene oxide (NiP-TiO2 sol -RGO) coated surface was successfully prepared by one-pot electroless deposition on the steel substrate. The results show that the homogeneously formation of water-repellent RGO film covering on the coated surface leading to improve the corrosion resistance and high electrical conductivity of NiP-TiO2-RGO coated steel. The second part is the development of GO nanocomposite coated textile substrates to enhance the analytical performances of non-invasive colorimetric sensor. GO nanocomposite was incorporated on textile substrates including fabric and thread by coating and padding. �The cotton fabric based sensor was successfully fabricated for sweat pH and lactate detection and it can directly apply onto the human skin for the simultaneous detection of pH and lactate during the physical exercise. The pH indicator gradually changed from red to blue as the pH increased, whereas the intensity of the purple color increased with the concentration of lactate in the sweat which can indicate the sweat pH in a range of 1-14 and the lactate level of 0-25 mM. As for the textiles, thread has been developed for non-invasive glucose and urea sensor. Thread is a promising microfluidic device for biosensor due to low volume of reagent and sample, fast reaction time and high sensitivity. This sensor can be used to identify the cut-off level of glucose (0.3 mM) and urea (65 mM) in human sweat. This sensor might be incorporated into clothes and accessories for the real-time and continuous monitoring of sweat biomarkers. This platform opens a new approach for non-invasive diagnosis in healthcare and it will be integrated with clothes and apparels for the users in the near future.
